Strap for Super Chronomat 38 Stainless Steel - Red Gold / Pink / Rouleaux

The Breitling Super Chronomat U17356531L1U1 features a 20mm lug width. This measurement is taken between the two lugs at the point where the spring bars are fitted. It is one of the most common lug widths in sport-elegant watchmaking, ensuring a wide selection of compatible straps in leather and other materials.

Given the combination of black ceramic, red gold, and stainless steel, the most suitable straps are: glossy black or tobacco brown alligator for formal wear, vegetable-tanned calf leather in black or dark grey for everyday use, shell cordovan in bordeaux or cognac for a distinctive mid-ground option, and vulcanised black rubber for maximum sportiness and water resistance. The ideal choice depends on the occasion and personal colour preference.

The strap is replaced by removing the spring bars from the lugs using a flat-blade spring bar tool or a lug lever. It is advisable to work on a soft surface to protect the case and ceramic from scratches. The new 20mm strap is fitted by sliding the spring bars into the lug holes. Those unfamiliar with the process are recommended to consult a watchmaker or the Casati Milano atelier.

Yes. Any standard 20mm strap with a straight end is compatible with the Breitling Super Chronomat U17356531L1U1. Milanostraps.it offers a curated selection of handcrafted straps in various materials — alligator, calf, shell cordovan, rubber — all with a 20mm lug width, designed to fit Breitling cases with standard lug profiles.

The lifespan of a leather strap depends on the material, care, and usage. A quality alligator strap, properly maintained and not regularly exposed to water, can last between three and five years while retaining a respectable appearance. Vegetable-tanned calf develops patina over time but is more susceptible to moisture. Shell cordovan is among the most durable options due to the density of its fibres. Casati Milano offers an 18-month guarantee against manufacturing defects.
